Neoclassicism in music was a twentieth-century trend, particularly current in the interwar period, in which composers sought to return to aesthetic precepts associated with the broadly defined concept of "classicism", namely order, balance, clarity, economy, and emotional restraint. As such, neoclassicism was a reaction against the unrestrained emotionalism and perceived formlessness of late Romanticism, as well as a "call to order" after the experimental ferment of the first two decades of the twentieth century. The neoclassical impulse found its expression in such features as the use of pared-down performing forces, an emphasis on rhythm and on contrapuntal texture, an updated or expanded tonal harmony, and a concentration on absolute music as opposed to Romantic program music.
In form and thematic technique, neoclassical music often drew inspiration from music of the 18th century, though the inspiring canon belonged as frequently to the Baroque and even earlier periods as to the Classical period--for this reason, music which draws inspiration specifically from the Baroque is sometimes termed neo-Baroque music. Neoclassicism had two distinct national lines of development, French (proceeding partly from the influence of Erik Satie and represented by Igor Stravinsky, who was in fact Russian-born) and German (proceeding from the "New Objectivity" of Ferruccio Busoni, who was actually Italian, and represented by Paul Hindemith). Neoclassicism was an aesthetic trend rather than an organized movement; even many composers not usually thought of as "neoclassicists" absorbed elements of the style.
Although the term "neoclassicism" refers to a 20th-century movement, there were important 19th-century precursors. In pieces such as Franz Liszt's À la Chapelle Sixtine (1862), Edvard Grieg's Holberg Suite (1884), Pyotr Ilyich Tchaikovsky's divertissement from The Queen of Spades (1890), George Enescu's Piano Suite in the Old Style (1897) and Max Reger's Concerto in the Old Style (1912), composers "dressed up their music in old clothes in order to create a smiling or pensive evocation of the past" (Albright 2004, 276).
Sergei Prokofiev's Symphony No. 1 (1917) is sometimes cited as a precursor of neoclassicism (Whittall 1980). Prokofiev himself thought that his composition was a "passing phase" whereas Stravinsky's neoclassicism was by the 1920s "becoming the basic line of his music" (Prokofiev 1991, 273). Richard Strauss also introduced neoclassical elements into his music, most notably in his orchestral suite Le bourgeois gentilhomme Op. 60, written in an early version in 1911 and its final version in 1917 (Ross 2010, 207).
Ottorino Respighi was also one of the precursors of neoclassicism with his "Ancient Airs and Dances" Suite No. 1, composed in 1917. Instead of looking at musical forms of the 18th century, Respighi, who, in addition to being a renowned composer and conductor, was also a notable musicologist, looked at Italian music of the 16th and 17th century. His fellow contemporary composer Gian Francesco Malipiero, also a musicologist, compiled a complete edition of the works of Claudio Monteverdi. Malipiero's relation with ancient Italian music was not simply aiming at a revival of antique forms within the framework of a "return to order", but an attempt to revive an approach to composition that would allow the composer to free himself from the constraints of the sonata form and of the over-exploited mechanisms of thematic development (Malipiero 1952, 340, cited from Sorce Keller 1978,[page needed]).[not in citation given]
Igor Stravinsky's first foray into the style began in 1919/20 when he composed the ballet Pulcinella, using themes which he believed to be by Giovanni Battista Pergolesi (it later came out that many of them were not, though they were by contemporaries). Later examples are the Octet for winds, the Dumbarton Oaks Concerto, the Concerto in D, the Symphony of Psalms, Symphony in C, and Symphony in Three Movements, as well as the opera-oratorio Oedipus Rex and the ballets Apollo and Orpheus, in which the neoclassicism took on an explicitly "classical Grecian" aura. Stravinsky's neoclassicism culminated in his opera The Rake's Progress, with a libretto by W. H. Auden (Walsh 2001, §8). Stravinskian neoclassicism was a decisive influence on the French composers Darius Milhaud, Francis Poulenc, and Arthur Honegger, as well as on Bohuslav Martin?, who revived the Baroque concerto grosso form in his works (Large 1976, 100). Pulcinella, as a subcategory of rearrangement of existing Baroque compositions, spawned a number of similar works, including Alfredo Casella's Scarlattiana (1927), Poulenc's Suite Française, Ottorino Respighi's Antiche arie e danze and Gli uccelli (Simms 1986, 462), and Richard Strauss's Tanzsuite aus Klavierstücken von François Couperin and the related Divertimento nach Couperin, Op. 86 (1923 and 1943, respectively) (Heisler 2009, 112). Starting around 1926 Béla Bartók's music shows a marked increase in neoclassical traits, and a year or two later acknowledged Stravinsky's "revolutionary" accomplishment in creating novel music by reviving old musical elements while at the same time naming his colleague Zoltán Kodály as another Hungarian adherent of neoclassicism (Bónis 1988, 73-74).
A German strain of neoclassicism was developed by Paul Hindemith, who produced chamber music, orchestral works, and operas in a heavily contrapuntal, chromatically inflected style, best exemplified by Mathis der Maler. Roman Vlad contrasts the "classicism" of Stravinsky, which consists in the external forms and patterns of his works, with the "classicality" of Busoni, which represents an internal disposition and attitude of the artist towards works (Samson 1977, 28). Busoni wrote in a letter to Paul Bekker, "By 'Young Classicalism' I mean the mastery, the sifting and the turning to account of all the gains of previous experiments and their inclusion in strong and beautiful forms" (Busoni 1957, 20).
Neoclassicism found a welcome audience in Europe and America, as the school of Nadia Boulanger promulgated ideas about music based on her understanding of Stravinsky's music. Boulanger taught and influenced many notable composers, including Gra?yna Bacewicz, Lennox Berkeley, Elliott Carter, Francis Chagrin, Aaron Copland, David Diamond, Irving Fine, Jean Françaix, Roy Harris, Igor Markevitch, Darius Milhaud, Astor Piazzolla, Walter Piston, Ned Rorem, and Virgil Thomson.
In Spain, Manuel de Falla's neoclassical Concerto for Harpsichord, Flute, Oboe, Clarinet, Violin, and Cello of 1926 was perceived as an expression of "universalism" (universalismo), broadly linked to an international, modernist aesthetic (Hess 2001a, 3-8). In the first movement of the concerto, Falla quotes fragments of the 15th-century villancico "De los álamos, vengo madre". He had similarly incorporated quotations from 17th-century music when he first embraced neoclassicism in the puppet-theatre piece El retablo de maese Pedro (1919-23), an adaptation from Cervantes's Don Quixote. Later neoclassical compositions by Falla include the 1924 chamber cantata Psyché and incidental music for Pedro Calderón de la Barca's, El gran teatro del mundo, written in 1927 (Hess 2001b). In the late 1920s and early 1930s, Roberto Gerhard composed in the neoclassical style, including his Concertino for Strings, the Wind Quintet, the cantata L'alta naixença del rei en Jaume, and the ballet Ariel (MacDonald 2001). Other important Spanish neoclassical composers are found amongst the members of the Generación de la República (also known as the Generación del 27), including Julián Bautista, Fernando Remacha, Salvador Bacarisse, and Jesús Bal y Gay (Pérez Castillo 2001; Heine 2001a; Heine 2001b; Salgado 2001a).
A neoclassical aesthetic was promoted in Italy by Alfredo Casella, who had been educated in Paris and continued to live there until 1915, when he returned to Italy to teach and organize concerts, introducing modernist composers such as Stravinsky and Arnold Schoenberg to the provincially minded Italian public. His neoclassical compositions were perhaps less important than his organizing activities, but especially representative examples include Scarlattiana of 1926, using motifs from Domenico Scarlatti's keyboard sonatas, and the Concerto romano of the same year (Waterhouse and Bernardoni 2001). Casella's colleague Mario Castelnuovo-Tedesco wrote neoclassically-inflected works which hark back to early Italian music and classical models: the themes of his Concerto italiano in G minor of 1924 for violin and orchestra echo Vivaldi as well as 16th- and 17th-century Italian folksongs, while his highly successful Guitar Concerto No. 1 in D of 1939 consciously follows Mozart's concerto style (Westby 2001).
Portuguese representatives of neoclassicism include two members of the "Grupo de Quatro", Armando José Fernandes and Jorge Croner de Vasconcellos, both of whom studied with Nadia Boulanger (Moody 1996, 4).
In South America, neoclassicism was of particular importance in Argentina, where it differed from its European model in that it did not seek to redress recent stylistic upheavals which had simply not occurred in Latin America. Argentine composers associated with neoclassicism include Jacobo Ficher, José María Castro, Luis Gianneo, and Juan José Castro (Hess 2013, 205-206). The most important 20th-century Argentine composer, Alberto Ginastera, turned from nationalistic to neoclassical forms in the 1950s (e.g., Piano Sonata No. 1 and the Variaciones concertantes) before moving on to a style dominated by atonal and serial techniques. Roberto Caamaño, professor of Gregorian chant at the Institute of Sacred Music in Buenos Aires, employed a dissonant neoclassical style in some works and a serialist style in others (Béhague and Ruíz 2001).
Although the well-known Bachianas Brasileiras of Heitor Villa-Lobos (composed between 1930 and 1947) are cast in the form of Baroque suites, usually beginning with a prelude and ending with a fugal or toccata-like movement and employing neoclassical devices such as ostinato figures and long pedal notes, they were not intended so much as stylized recollections of the style of Bach as a free adaptation of Baroque harmonic and contrapuntal procedures to music in a Brazilian style (Béhague 2001a; Béhague 2001d). Brazilian composers of the generation after Villa-Lobos more particularly associated with neoclassicism include Radamés Gnattali (in his later works), Edino Krieger, and the prolific Camargo Guarnieri, who had contact with but did not study under Nadia Boulanger when he visited Paris in the 1920s. Neoclassical traits figure in Guarnieri's music starting with the second movement of the Piano Sonatina of 1928, and are particularly notable in his five piano concertos (Béhague 2001a; Béhague 2001b; Béhague 2001c).
Even the atonal school, represented by Arnold Schoenberg, showed the influence of neoclassical ideas. The forms of Schoenberg's works after 1920, beginning with opp. 23, 24, and 25 (all composed at the same time), have been described as "openly neoclassical", and represent an effort to integrate the advances of 1908 to 1913 with the inheritance of the 18th and 19th centuries (Cowell 1933, 150; Rosen 1975, 70-73). Schoenberg attempted in those works to offer listeners structural points of reference with which they could identify, beginning with the Serenade, op. 24, and the Suite for piano, op. 25 (Keillor 2009). Schoenberg's pupil Alban Berg actually came to neoclassicism before his teacher, in his Three Pieces for Orchestra, op. 6 (1913-14), and the opera Wozzeck (Rosen 1975, 87), which uses closed forms such as suite, passacaglia, and rondo as organizing principles within each scene. Anton Webern also achieved a sort of neoclassical style through an intense concentration on the motif (Rosen 1975, 102). However, his 1935 orchestration of the six-part ricercar from Bach's Musical Offering is not regarded as neoclassical because of its concentration on the fragmentation of instrumental colours (Simms 1986, 462).
Some composers below may have only written music in a neoclassical style during a portion of their careers.
